Abstract

Système de reconnaissance et d'identification de sources sonores en temps réelLa présente invention concerne un procédé d'identification d’une source sonore comprenant des étapes suivantes :S1 : acquisition d’un signal sonore ; S2 : application d’un filtre fréquentiel au signal sonore acquis de sorte à obtenir un signal filtré ;S4 : extraction d’un ensemble de caractéristiques associées au signal filtré ;S5 : identification de la source en appliquant un modèle de classification à la matrice de caractéristiques extraite à l’étape S4 le modèle de classification ayant comme sortie au moins une classe associée à la source du signal sonore acquis. Figure pour l’abrégé : Fig. 1Real-time sound source recognition and identification systemThe present invention relates to a method for identifying a sound source comprising the following steps:S1: acquiring a sound signal; S2: application of a frequency filter to the acquired sound signal so as to obtain a filtered signal; S4: extraction of a set of characteristics associated with the filtered signal; S5: identification of the source by applying a classification model to the matrix of characteristics extracted in step S4 the classification model having as output at least one class associated with the source of the acquired sound signal.
